Abstract
The authors investigated the possible relationship between depression and alexithymia in a population of hospitalized patients suffering from Parkinson's disease (PD). Fifty-eight PD patients without dementia participated in the study. Alexithymia was screened using the 20 item version of the Toronto Alexithymia Scale (TAS 20). Depression was diagnosed using a Structured Clinical Interview (SCID I) for DSM-IV. Severity of depression was evaluated with the Beck Depression Inventory (BDI). The prevalence of Alexithymia was about 21%. PD patients with major depression were significantly more alexithymic (TAS 20 average score = 61.4) than PD patients without depression (TAS 20 average score = 47.4) and, also, tended to be more alexithymic than PD patients with minor depression (MiD; TAS 20 average score =50.6), whereas no difference was found between PD patients with MiD and PD patients without depression. Moreover, high scores obtained on the BDI were found to strongly predict high level of alexithymia in these patients. These results extend to a cohort of PD patients previous data from the literature evidencing a strong association between alexithymia and severity of depressive symptoms.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
